To dll whom it may concern:

Be it known that I, JOHN H. MOREL/mo, a citizen of the United States, and a resident df Altoona, in the county of Blei r and State of Pennsylvania, luwe invented certain new and useful improvements in Antifriction-Bearings, whereof the following is a specification, reference being had to the accompanying drawings.

This invention particularly relates to antlfriction` bearings of a class technically known as roller or ball bearings, und is especially adapte for use in connection with car Wheel journals-r Theprincipal object oi' this invention is to provide a simple and etiicent antifriction bearing in which the parts are held together to form a unitary structure which may be readily adjusted to and/removed from a shaft or journal, as such.

Other objects of this invention are, to provide complementary bearing members respectively having ball races vwhich are adjustable transversely with respect to the anis of the bearing; to provide a mounting for the bearing members arranged to permit u relative .rocking movement between the bearing and its support; to provide seatsdor said bearing disposed in a position to; re venttwisting of the bearing; to proide bearing members which are automatically adjusted to take up the wear; to provide means to limit the relative movement of sani ing all races Ywhose wearing surfaces are "greater at the region of greatest wear; tp

races therein, and arranged to convey oil by capillaryattractiomto said races, and to convey gritor dirt therefrom; to provide an oil receptacle disposed in such relation tov said apertures asto readily permit oil-,to

l flow therein; to provide a mounting forthe bearing members lhaving means to maintain in alinement the ball races of the respective bearing members; to provide adjustable means to retain -said bearing members in operative relation: to provide means to premelpers; to provide bearingmembers hav-- vent the accidental displacement of said adjustable means; to provide dustsguards operative to protect the bearing members; to provide a casing for the bearing to provide .a dust-guard for said casing having a packing pocket surroundin the shaft in said bcaring;' and to provi c a closure for the open end. of said casing, hingedly secured thereto and disposed in vertical position when closed, and maintained in closed position by snapping its edge over the edge of said casing.

The form of this invention hereinafter described is particularly adapted to be applied to a car wheel journal, n nd inrhules a bear ing formed as hereinafter described, having a sleeve snugly lifted to said journal and secured thereto by slipping the bearing over said journal and binding said sleeve thereto by nuts engaged with threads on the free end of said journal.

Further objects of. this invention lare, to provide dust-guards havinlgr a. frame relativelyfixed with respect to the 7relatively stationary bearing members, and having a, movable plate surrounding the shaft or journal and movable in accordancegwith any displacement of the axis thereof; 'to provide said dust-guards with separate split plates disposed upon opposite sides of said shaft, each having a semi-circular recess embracing said shaft, and provided with undercut hall races Whose overhanging edges prevent displacement of said balls when removed from said shaft. l

This invention also includes all of the various novel-features of construction and arlangcment hereinafter more definitely speci- In the accompanying drawings, Figurel is a plan view of a bearing constructed in accordance with this invention, mounted on a journal Within its casing; Fig. 2 is a longitudinal sectional view of the bearing shown in Fig. 1, taken along the Vaxis of said journal, the journal being shown in elevation for convenience of illustration; Fig. 3 is a transverse vertical staggered sectional view on different planes in Fig. 1; Fig'. 4 is n fragmentary pers ective view,`looking into the 'u pper corner o the bearin casing; Fig. 5 is a central longitudinal sect1onal perspective view ofthe bearing mountin or saddle; Fig. "6 is a fragmentary side e evational view of said mounting4 or saddle; Fig. 7 is an end view of the semicylindrical upper bearing meinber; Fi 8 `is a fr entary inverted plan view ogf the barinsxiilember shown in Eig. 7;'Fig. 9 is a` side elevation of one of theend lowerA bearing members; Fig. 10 is a plan view of the bearing member shown in Fig. 9; Fig. 11 is a central vertical transverse sectional View taken on the line 11-11 in Fig. 10; Fig. l12 is a side elevation of one of the intermediate lower bearing members; Fig. 13 is a lan vi'ew of the bearing member shown in ig'. 12; Fig. 14 is a fragmentary plan view showing one corner ofthe oil receptacle;` Fig. 15 is lr fragmentary plan view showing one corner of the supporting. plate arranged to retain the oil receptacle and bearing members in operative positiorrfin the mounting; Fig. 16 is a sectional elevational view of one 0 the adjustingscrews for retaining the bearing members in operative position; Fig. 17 is a` locking plate arranged" to ,prevent accidental rotation of the adjusting screws, and'Y Fig. 18 is a fragmentary central sectional view showing the bearing members having different circular extent.

In said figures the axle 1 has the journal 2, upon which the bearing sleeve 3 is secured by the nut 4, bearing upon `the collar 5, which is fitted in a shoulder 6 in said sleeve 3. Said nut 4 is in threaded engagement with the threads 7 on the reduced end of said journal 2 and is l'ii'evented from accidental Idieplacement by the nut-1ock 8, which l1s held engaged therewith by the jam-nut 9201i the threads 10.

The sleeve'` 3 is provided with the spaced, ball races 11 for the bearingballsv'12, and is (provided with flanges 13 at its'ro posits en s, having opposed curved shoul ers 14, to'provide races for the thrust balls 15. Said sleeve 3 is embraced by the semi-cylindrical bearing member 16, .having ball races 17 complementary to the ball races 11 in the sleeve 3, and having iianges 1.8 whose outer edges overhang the lianges 13 on the sleeve 3 and have curved shoulders therein opriosed tor they curved shoulders I4 in the' sleeve. A3, and arranged to form .ball races for the thrust bearing balls 15.

.The flanges 18 of the bearing member 16 -are fitted into suitable Vrecesses 2O inV the mounting or saddle 21, and said bearing member 16 is also provided withjhe later- .ally eigtending flanges 23V substantially in a plane with thenxsI ofthe journal 2, and having projecting ribs 25 fitted into the vertically disposed channels 26 in the mounting 21, said fianges 23 serving to prevent `rotation of the bearing member 16.by eng'genignt with the shoulder 27 ,in said mounting, and said ribs"25 and flanges.v 18

serving to prevent"y longitudinal ldisplacement* of sald bearing member 16.', This be-.irilnginiember 16 ,yelriesgiI Width through- 'l -be allowed to wear considera Vout Aits transverse section; that is toL say, it

` ,the sleeve 3 is to wear the bearing member greatest at the top and to impose a constantly decreasing wear upon the same downV to ,the sides, By making then this bearing member 16 thicker at its crest the same .may

bly; that is to say, until the vchannels forming the ball race approach a curve concentric with the outer surface of the member 16 `and when so worn, the bearingmember 16 will'be as thick at the top as it will be at theV sides. a plurality of thrust ball races disposed 1n The lower half of. the sleeve 3 is embraced by the bearing members 30 and 31, whose ball races 32 are complementary to the ball races 1l; the bearing members 31 each being further provided with ya curved shoulder 33 in opposition to *the respective curved shoulders 14 in the sleeve 3, and formin a race for the thrust balls 15. Each of the bearing members 30 has two ball races 32 therein, which are provided with `a central groove 34', in communication with an' elongatedaperture 35 at the bottom thereof and Awhich Aextends downwardly through said bearing members for the escape -of`d1rt and grit :from said ball races, and for tie escape of any7 of the broken or crushed ba therein. Said apertures 35 and oves 341 also provide suitable passa ways for the races 32, the wear therein will beisu-bstantially equaLto the vean-ini the region of greater pressure.`

As best shownin Figs.`,y`i0,`12 and 13., the "bearin members 30 and 3l have lateral' ribs? an 38respectiyely, which are iitted 1n the channels 26 inqthe mounting 21- to maintain saidbearing members in"l a position with respect to ,the semi #cylindrical bearin member 16, to register the ball races 32 wit `the ball races 17,

As bestV shown in Figs. 12 and 13, the latf eral ribs 37 of the bearing" members 30 `are provided with grooves 39 for the esclip'epi oil from the ball races, which arffords a free circulation of oil upwardly to the oil receptacle 42; The oilfrece tacle i iroilgh thb'np- "trium 35 mi buf-k thmuehthe armes 42 has a yrim. 43 iexteitlin abdye` the ower portions of the bearingy members 30 and. 31,`

`and provides' a receptacle for oil'ydwaste '451i i Said oil rece tacle 42 is provided with hol low threads internal and external alined bosses-47 and 48 respectively, in which the adjustable screws 50 are fitted. Each of the screws 50 has a reduced extension 51 projecting into an alined socket 52. The respective sockets are disposed in the lower face of the bearing members 3() and 31, centrally' between the ball races, said extension projecting into close proximity to the inner wall .of said socket and being surrounded by a coiled spring 53, which is seated in a groove or de ression in the top of the screw 50, an which serves to normally retain the bearing members 30 and 31 in their operative ositlon against the balls in the races 32. he adjusting screws 50 are each provided with a squared extension 56, and are rovided with lock-nuts 57 and prevent ed rom rotation by lock-plates 58, which,

las best shown in Fig. 17, are provided with a' plurality of square apertures 60 adapted to fit over 'the squared extensions 56 of the alined adjusting screws 50, as best shown in Fi 2. As shown ,in Figs. 2 and 3, said loc -plates are retained upon the squared extensions 56 by suitable pins or cotters G1, which are driven through apertures 62 near the outer extremity of said squared extensions 56. 'The oil receptacle 42 and the parts upheld thereby are supported by the supporting plate 64, which, as best shown in ig. 15, is provided with apertures 65 for the reception of the exterior bosses 48, whie when thus engaged prevents the displacement of said .supporting plate 64,;which is supported at its edges ina channel or groove 66, as best shown in Figs. 3 and 5.

As best shown in Figs. 2 and 15, the supporting' p'late 64 is provided with lugs or extensions 68 Whose outer edges terminate coincident with the end surfaces of the'fsif said journal, will not be effective` to acciniounting ,or saddle 21 and are arran ed to support the dustuards 70, whic are mounted in channe s 71 at the end of the mounting or saddle 21,`and whichwill be hereinafter described in detail.` ,p l

The structure thus' far described com- 'prises the bearing proper, which may be se. 44cured to the` journal 2 and removed therefrom as' a unitary structure, and when ad justed on the journal 2, as best shown in Fig. `2, isinclo'sed in the casing 75, which has a concave upper wall fitted to the convox 4supportin surface 7f3 of the mounting 21,-so asto a orda free rocking 4movement of the `journal@ in .a vertical plane. Said convex `surface terminates laterally in parallel shoulders78., vwhich are in parallel re.-

lation with the .axispf said journal, and

which are disposed loosely between the parallel shoulders 79 in thecasing 75, as best. shown inFigs. 3 and 4, so'as to permit a slight lateral movement .'of the bearing with respect to its casing. In order to prevent a twisting movement of the bearin in casing, the mountin 21 is provi ed with laterally disposed side lugs or saddles 80 projecting into the recess 81 in the easing 5, as best shown in Figs. 3 and 4, and having a curved upper surface 83, u on which the seat 84 of said casing rests, t us giving the supporting casing three points of supn port upon the bearing mounting 21, which as a slight sliding movement in the casing laterally, and is free to rock or slide in a plane parallel with the axis of the journal 2, whereby a dropping of the axle 1,incident to the inequalities of the roadbed, may be accommodated without injury to the earing members, and whereby the wheel is free to vibrate laterally. The casing 75 is provided with opposed channels 85, as best shown in the inner end of the casing 75and which4 embraces the axle 1, and is so constructed as to permit said axle to move eccentrically with respect to its normal axis, without buckling or otherwise straining said dustguard 86.

The opening in the outer end of the cas ing 75 is provided with a closure 128, formed preferably of a sheet, metal stamping and hingedly secured .by the pintle 129 to the top upper edge of said casing 75, and provided with a spring edge 130 at its bottom edge for engagement with tbe beadin 131 extended along the lower out edge o said casing 7 5, whereby said closure 128 may be snapped into and out of engagement with said beading 131 to lock or unlock said closure 128, as desired. -It may be here noted that by reason of the vertical position of the closure 128, the continuousvertical jar lof the journal, incident to the inequalities of the roadbed being traversed by the wheels guards 70, which are disposed. at the opposite ends of' the anti-friction bearing, are

similar to the dustguard 86 above described,

with the exception of the outer frame 135.

which, as best shown in Fig. 22, is provided with depending feet 136,. which are supported by the lugs or extensions 68 of the supporting plate 64. as best shown in Fig. 2, and said frame has only its vertical bars Ilanged, which permits the outer .plates to extend flush with its 'upper edge and -to'extend below its lower edge. as best shown in Fig. 2; furthermore, the dust-guards 70 do not include a dust-guard B6.

packing pocket, as does the Referring to Fig. 2. it will be readilv seen that by placing a' jack 140, as shown in.` dot and dash lines in said figure, beneath the truck frame 142 and raising the casing 15.V suiciently to clear the surface 76, the antfriction bearing may be disengaged from the journal 2 b v removing the nutsl 4 and 9 and slidn said bearing therefrom, so that a defective bearing may be readily removed i and replaced by a pei-feet 'bearing without withdrawing lhe ear from Servire. 'It may' be observed thatbearings eonstrueted in aeeordanee withithis invention may be assembled at the shops and shipped to various points along the line For use in ease of emergency. The. assembling ot' the bearing is eonveniently etfeeted by inverting the mounting 2l and inserting the bearing meinber 16 in the pocket provided therefor. the balls l2 being then laid in their resl'ieetive rares. forming a haltl series, whereupon the. .sleeve-3, having the dust-guards 7l) slipped over the llanges lll at its opposite ends, is laid upon said bearing balls by sliding the dust-guards iulo their respective channels T l. The balls 15 are, then dropped into their respeetive races `formed between theI curved slionllflers '14 und 10. Theienuiiiiing bulls are then laid in the. ball rares ll and the bearing members 1:50 and il slid thereorer with their respeetive lateral flanges 3T and le in engagement with the rhannels 2li in the mounting 2l. l'laving thus built up the bearing` the pil reeeptzu'le l2 is then slipped into position with its lateral llanges in engagement with said rhauuels 2li. aiter whieli the supporting plate (il is slid endwise in the rhannel'ti until its apertures register with the exterior bosses i8 on said oil receptacle 4L. whereupon 'the springs 53 are dropped intothe soeli'ets 52 and the adjust` able sel'ews 5() are inserted in the threaded apertures in the bosses 4T and 4S and :uljusted to ell'eet the desired pressure upon the bearing members 2i() and I whereupon the ioeli-nuts oT are udjusteih the lorliing-plate 5b mounted ou the squared extension 5G, and the ruiter pins (il inserted to hohl said loeliingplale in engagement therewith. ln assembling this bearing` it is to be observed that the adjaeent edges nl' the bearing inemberlli and the series of bearing members till. ind H1 are at first slightly spared apart as dearly shown in lfig. il. 'lhe purposeo this is to permit the members El() and :All to take up the wear as the. balls deepen the ehannel in the top bearing member lt. 'lhis spaee between the adjiieent edges ot' the to'p and 4bottoni bearing members in no wise elieets the action of the balls in the rare-ways. Theoreticallygthe ballsat and below the horizontal plane iriassing through the, axis of the: shaft 2 lo not supliort the load` and` therefore. are not subject to great pressure between the, bearing members 1G., 30 and 31k and the inner sleeve il. 'lhis space, between the adjacent edges ot' the bearingmeinbers is', ot eourse, not greata's rompared with the. diameter of the balls and the separation of the adjarent edges shown in Figxl is on an exaggerated Scale for the salte of elearness in illustration.

Although the bearing chosen for illustration is particularly applicable to n car wheel journal, it is to be understood that it may be conveniently adapted to any rotatable mechanism, and therefore it is not desired to lilnit this invention to the precise details of' construction and arrangement herein set forth, as it is obvious that various modifiY rations may be made therein without departing from the essential features ol.' the invleution as defined in the appended elsiiuis.
